[PATCH 0/3] ALSA: scoped cleanup improvements for ALSA core

["Cássio Gabriel" <cassiogabrielcontato@gmail.com>]

This series converts a few local ALSA ownership patterns
to scoped cleanup helpers.

- The first patch uses __free(kvfree) for temporary user control buffers
in the ALSA control core.
- The second patch promotes the existing local snd_card_unref cleanup
helper to the common ALSA core header and uses it for temporary card
references in the control layer.
- The third patch applies the same idea to the temporary OSS sequencer
MIDI use-lock reference added for embedded SysEx event lifetime handling.

These are cleanup/hardening changes only. No functional change is intended.
